A seasonal waterfall (reported around 45 feet) in a box canyon at the eastern end of Starved Rock State Park, often combined with neighboring Kaskaskia and Illinois Canyons. A short hike of about one mile reaches the falls from nearby parking off Route 178.

Its 45 ft drop is taller than about 35% of the 775 waterfalls we track.

Ottawa Canyon Falls sits on seasonal canyon stream. It lies in La Salle, Illinois. The site is on public land managed by Starved Rock State Park (Illinois DNR).

This is a short hike waterfall: reached by a short trail, generally under about a mile each way. The walk in is brief — comfortable shoes are usually all you need. The walk to the main viewpoint runs about 1 miles round trip. The nearest town is Utica.

When to go: Spring (after rain or snowmelt). Water volume swings with the seasons here, strongest after snowmelt or rain and lowest in late summer, so check recent streamflow before you go.
